ALFRED S. EMERSON'fOF LONDON ENGLAND v i SNOW-MELTING MACHINE.

5170 alt whom it may concern; I

Be it known that I, ALFRED S. Ennnsox, a

citizen of the United Stat-es, residing at London, England, have invented certain new and useful Improvements in Snow-Melting Machines, of which the following is a. specification.

This invention relates to street cleaning apparatus, and more particularly to a device for removing the snow from the streetand for nelting the same.

The invention has particular reference to th'e mecha-n isin for scraping up the snow from the street and conveying this into receptacle which is in the fornrof a tank and to the furnace mechanism for heating this tank for reducing the snow to water.

In the drawings accompanying and forming .a part of this specification Figure 1 is 'aside elevation of a practicable embodiment of a form of my invention, certain of the side walls are broken away in this view to show the interior construction section of the device illustrated in Fig. 1, taken in about the center of this view. This Fig. 2 is a cross view is somewhat enlarged over the showing in Fig. 1; hand end of the tank andsurrounding struc tures illustrated in Fig. 1' This view is .mostly in vertical section, but taken on several planes, for instance the smoke stack is Q broken into vthe tank, flue and fire boxes are shown beyond this, each broken into at a diil'ereiit plane.

upon and carried to a point within the receptacle where it will by a scraper l2'which precedes the conveyer drop the snow'whi'chhas-been delivered to it belt and scrapes the snow up and the snow will ride up on this scraper until it comes to a 1 position where the conveyor buckets will be effective to receive itand convey it into the receptacle or tank. The'tank is intimately associated with a furnace. 'In the present instance the fUIIlfiCQlS made up of a number of furnace units. randeach furnace unit is shown as COIlIPfibRYgJLfITQ chamber or fur- Specificationof Letters Patent.

out through a'suitable vent And Fig. 3 is a detail of the left the tank in the present instance constitute the'saine plate 15.

The flames and which may be above it, will pass on into-the flue portion 16, the roof of which also constitutes the floor of another portion of the tank and is embodied in the plate 157;. :The vari ous furnace chambers are 'separatedby walls 18 of resistant material, butthe flue portions are separated bymeans of side wallsltl of the .tank and between whiclrs 'de ,walls is a space 20 which mayrece ve water, The

wateriii the immediate vicinityof thewallse of the furnace chamber and of the lines will be raised to a high temperature and will form steam which will assist in the melting of the snow and the heating of the water from the snow which liasbeen melted.

A pocket or mud drui-n 21 is provided at Patented May 26, 1908.

heat from thefurnace will pass along this floor 15-,l163LlDg tl16 water;

the rear of the furnace chamber in the tank and into this will settle such niu'd as may be taken up with the snow. This may be let 22froin which ventwater will also be ejected, when the deemptied there or any convenient place which may be chosen. The water, of course. coming out at a opportunity to escape into the sewer before again'freezing. By having this inud receptacle the mud walls of the tank through which the heating of the water is effected and by this means the mud will not be permitted to insulate the heating walls. This mud pocket or drum is shown as having considerable area atthe position 23, which is immediately below the point of delivery of the conveyer belt. .By

. this means the mud carried in with the snow will immediately sink into the drum without being carried into the portions of the tank where it will foul the heating surfaces. I

The perforated pipe 25 is located at a point wheretlie'horizontal fine 16 turns into the, vertical sinoke'stack 26. The small arrows 27 indicate the passage of the unconsuined portions .of fu'el' and gases which will travel along the upper part of this horizontal portion of the flue and find ready entrance into the'perforat-ions' of the pipe 25 and will be drawn do vn the pipe 27 by means of'the steam injector 28 and will be discharged behigh temperature will have an will be kept away from those I low the furnace grates and be bassed through the fire by means of the draft of the fan 29 which may be driven in some convenient manner, as for instance by means of a steam turbine.

When it is desired to raise the scraper for any purpose, as for instance, t0 cha-ng e its positlon ot working or to put it 111 an 1110 erative position a hand lever 31 near the drivers seat 32 may be actuated, which by means of a connecting bar 33 will act on the long end' of a lever 34 which is linked at 35 to the hood S and will thus raise the hood and scra er or lowerthe same as occasion may demant V The floor 24 of each of the horizontal fiues constitutes the roof plate of a portion of the tank. The portions 35' of the tank are in the nature of boiler tubes. Having described my invention 1 claim:

1. The combination with a furnace grate,

fire chamber and furnace fine, of a tank surroundingsaid flue and having a floor which constitutes the roof if the fire chamber, means for scraping .up snow, and means for 2.- T 1e combination with a plurality of indefp'en'den't furnaces, each comprising a grate,

re chamber and a furnace fine, of a tank surrounding said fines,- the walls of which constitute the sides of said fines being separated between the ad acentfl'ues to leave a space for water, said tank having a floorwhichconstitutes the roof of the fire chamber, and

portions of which constitute the roof and floor of each of'the flues, a smoke stack communicating with all of the fines, a blower for each of said grates, and means for removing snow from a road surface and conveying the same to said tank, and a carriage upon which the same is mounted.
